Introduction: I work in central-northern Canada (Lloydminster area) as an oil-well operator. I make sure that the oil is flowing to the surface, and take care of shipments blah blah blah. My employer, also owns a radiator repair shop (for the radiators inside the skid houses that keep the motor cool that rotates the rods that are going "down hole") I work in his shop as well, and have helped build, and repair such sized radiator. Most of which are 4.3L BMW to 5.9L Bucks/ Atlas radiator, all the way up to a 8.3L Cummins. I had some free time, so decided to build a small scale radiator, that would fit in my TJ07 that I am rebuilding. Now, you guys need to understand, that this one, of this size, is my first run at it, and not 100% complete yet. This is more of a prototype than anything. Just trying to experiment with my own knowledge and skill... I think I succeeded. Now that I know how my work turns out, I can increase my own expectations and push my limit on the next one.

This one I am showing you is 11FPI - though it seems a little tight. It looks more tight because the way the tubes are, and also because the tubes are quite large; 3/4in to be exact. As for the tubes, they are staggered. I all ready know I will need some high CFM fans to get through. This one is also a single pass design. Why? Because you cant make a duel-pass with staggered tubes - or at least, with my skill, I can't. It has copper tubes copper fins, and brass tanks. The fins are a flat dimpled fin design - used to cool gen sets, buses etc. The tanks where a quick mock up pair though - just cut, snipped, folded, and soldered the corner. What is usually done, is that the are cut, rounded, and soldered with silver - it then looks like one solid piece. It's in the shape of a 120.4 but with a lot more thickness and a little more length. It's around 3.5" thick, or three Swiftech radiators. Oh, as for those tube this is what I mean by staggered; If you took the tob tank off, and look down on to the top of it, it would look like this: (the underscore is just there so I can push it in)

My next revision, 8FPI, single row tubes, duel pass, triple, or quad pass (couldn't make it because of the staggered tubes), and probably only 3 rows. Tanks will be soldered together with silver so they look like one piece, with no abnormalities.

Current Specs:
Copper Tubes
Copper Fins - Flat dimple finned design. The inside of these have little "slits" - much like on the inner side of the serpentine finned rads.
11FPI
Staggered 3/4" tubes
Brass tanks
G1/4 threads
Single-pass

Thanks Jibz
I needed a rad for the bottom of my TJ07 (which is my project while I wait on my parts for the Little Devil PC-V8), As much as I love the HardwareLabs SR-1 480mm rads (I have three all ready!) I just felt that I needed something a bit different.

This one is just big enough to fit the entire length of the bottom of my TJ07, while taking up half the width (the PSU is being moved elsewhere). There is enough room for the fans, and watercooling equipment. Anyways, that isn't important.

Just need to take some good pictures of it. I must say. I am quite happy with how the paint turned out. I primed it, painted it then went over it with the spray gun far away so the "mist" of the paint coated it. Gave it a "textured" finish. Think TJ07 exterior - actually, it matches perfectly.
